Red Hat Security Advisory: python-kdcproxy security update
Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fix(es): * python-kdcproxy: Unauthenticated SSRF via Realm?Controlled DNS SRV (CVE-2025-59088) * python-kdcproxy: Remote DoS via unbounded TCP upstream buffering (CVE-2025-59089) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The python-kdcproxy component in Red Hat Enterprise Linux 7 Extended Lifecycle Support contains two security vulnerabilities. CVE-2025-59088 is an unauthenticated SSRF vulnerability that can be triggered via realm-controlled DNS SRV records. CVE-2025-59089 is a remote DoS vulnerability caused by unbounded TCP upstream buffering. Red Hat has released updated python-kdcproxy packages to address these issues. The advisory references Bugzilla entries BZ-2393955 and BZ-2393958 for the respective CVEs and directs users to apply the provided updates.
Potential Impact
Successful exploitation of CVE-2025-59088 could allow an unauthenticated attacker to perform SSRF attacks, potentially leading to unauthorized internal network interactions. CVE-2025-59089 could allow a remote attacker to cause a denial of service by exhausting resources through unbounded TCP buffering. Both vulnerabilities affect the stability and security of systems running the affected python-kdcproxy versions on Red Hat Enterprise Linux 7 Extended Lifecycle Support.
Mitigation Recommendations
Red Hat has released updated python-kdcproxy packages (version 0.3.2-3.el7_9.3) for Red Hat Enterprise Linux 7 Extended Lifecycle Support that address these vulnerabilities. Users should apply these official patches as detailed in the Red Hat advisory (RHSA-2025:22982) and the update instructions at https://access.redhat.com/articles/11258. No alternative mitigations are indicated in the advisory.
